I recall there were issue because /cygdrive on Cygwin is accessible, but is 
not shown when you list content of /. But I that that's fixed.
And there were issue because on Cygwin such special files like /cygdrive have 
'0' is modification time, but that's fixed too. I guess it's another cygwin 
moon-phase related quirk.
